EYEGLASSES.

To all whom it may concern:

Be it known that I, LEO F. AM, ,of the city of, Albany, in the county ofRensselaer and State of New York, have invented certain new and usefulImprovements in Eyeglasses; and I dohereby ,cleclare the following to bea full, clear, and exact description of the same, reference being had tothe accompanying drawings, forminga part of the specification, and tothe reference-numerals marked thereon. a

This invention relates to eyeglasses of the type in which the lenses areconnected by a substantially rigid support holding them against relativemovement, and the nose guards are arranged to swing thereon and areoperated by extensions serving as finger pieces; one object of theinvention being to provide a mounting in which the support has springportions acting to position the nose guards and also, if desired, toretain the guards thereon; and a further object being to provide noseguardshaving shiftable fulcrums which cause the guards to move away fromthe nose quickly at first and then slowly, thus expediting the removalor the positioning of the eyeglasses without increasing the length ofmovement of the nose guards.

To these and other ends-the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fully'described, the novel features being pointed out in the claims at the endof the specification. Y

. In the drawings: Figure 1 is afront view of a 'pair of eyeglassesconstructed in accordance with my invention, parts being shown insection; Fig. 2 is a top view of the same embodiment; the guards beingshown in different positions; Fig. 3 'is-a central transverse sectionofthev same embodiment; Fig. 4 is a top view of another embodiment; Fig. 5is a front view of the'mounting of the same embodiment showing parts insection, and Fig. 6 isa-cent-ral transverse section of the embodimentshown inv the last two figures.

The invention which is susceptible of be-' Specification of LettersPatent.

. caused to first portion preferably in the form of lugs which aresuitably secured to lens attaching members 3 of any desired constructionforming part of the support and each having,.in this instance, edgebearing portions extending in opposite directions to coiiperate with theedge of a lens. The nose guards C are mounted on the support and eachpreferably rests on a seat formed by one of the lugs 2 and has a rockingbearing on the support, or in other words, has a shiftable fulcrum,whereby the nose engaging member is move quickly away from the nose andthen slowly so that the removal of the eyeglasses may be expeditedwithout increasing the length of movement of the guards. In the or edge13 on a guard which bears against a fiat face 011 the inner or proximateside of the edge bearing portion of a lens attaching member, the guardbeing held against vertical movement 011 the seat 2 by an overhanginglug l4 projecting inwardly over the seat from the edge bearing portionof the lens attaching member and forming with the said seat 2 an openbearing.

The nose guards are positioned and at the same time held on themountingby spring portions of the support which are made preferably from thestock from which the bridge is formed. In this instance the flat stockat each end of the bridging portion is extended rearwardly andhorizontally at 4 and is bent flatwise outwardly as at 4*, forwardly asat 5, and inwardly as at 6 and thence forwardly to provide a forwardlyex-- tending spring arm 7 above the seat 2, the

Several bends being employed to form a horizontal loop deflectedpartially inthe rear of a lens so that it will be inconspicuous and atthe same time give suflicient spring to the forwardly extending springarm 7. At its free end, each arm 7 has a vertical projection 8 extendingdownwardly to engage within an opening 9 in the forwardly projectingoperating arm 10 of one of the nose guards to form a detachableconnection I therewith. In positioning the eyeglasses the Patented June6, 1911.; Application filed June 21, 1907. SeriaLNo. 380,027.

present instance, the rocking I bearing comprises a vertical curvedport1on ends of the operating arms 10 arepressed toward each other, andthe glasses are placed in a position so that the nose may be engaged onopposite sides when the operatlng arms are released, and in removingthe.

glasses the operating arms are again pressed together. To separate theguards from the rest of the mounting the projections 8 on the arms areremoved from the openings 9 and the guard is withdrawn rearwardly fromthe mounting. I

In the embodiment shown in Figs. 4 to 6 the lenses A are connected by asubstantially rigid support B the bridge of which is formed from flatstock bent 'to provide an arched bridging port-ion 15 and a verticalopen bearing 16 at each end, each bearing being made from a forwardlyextending arm at the end of the bridging portion rolled rearwardly andrigidly secured to one of the lens attaching member 17 which may be ofany suitable form. Supported on the seat formed by each bearing 16 is anose guard C which has a forwardly projecting operating arm 18, and arearwardly extending nose engaging member consisting of the upper pad 19and the lower pad 20. Each guard carries a pivot pin 21 to depend intoone of the open bearings 16, and is held to thelatter by a springportion on the support which also serves to positionthe guard like asimilar portion on the first described embodiment. The spring portionsin this instance extend rear- Wardly from the ends of the bridging.portion and are each made from the fiat stock which is bent flatwiseoutwardly at 21 and slightly downward edgewise to a forwardly extendingbend 22, thence inwardly horizontally at 23 andfinally outwardly toprovide a forwardly extending spring arm 24 arranged beneath the bearingportion of the bridge. At its free end each forwardly ex tending springarm 24 has a vertical or up ward extension 25 which engages theoperating arm of a nose guard by overhanging the inner edge of thelatter at 28, thereby retaining it in place upon the support. Theoperation in removing or positioning the eyeglasses is the same in thisembodiment as in that first described butthe guards are separated fromand fitted to the-support in a different manner. move theguards the freeends of the arms 2& are moved toward each other so that the overhangingportions 26 will be moved to positions to permit the guards to bevertically withdrawn from the open bearings.

The invention herein disclosed provides eyeglasses whichare inexpensiveto manu facture and simple to manipulate. The

parts are few and the separation or assem- 'bling thereof iscomparatively easy as the use of separate springs and 'small screws orother fastening devices is dispensed with, except in the fastening ofthe lenses.
